To all whom it may concern.'

` Be it known that I, HARVEY K. 'ERNS- BERGER, a citizen of the United States residing at Norwalk, in the county of Huron and State of Ohio, have invented a new and use ful '.WatenHeater, of which the follojwing is a specification.

This invention relates to Water heaters and its Objectis to provide simple7 compact and efficient, means whereby the temperature of Water y within. the heater may be quickly raised by the use of a minimum amount of fuel.

ftofo're Wasted is utilized for raising the tein-` i A still further object Vis to provide means whereby a large percentage of heat hereperature of the Water.

A still further object is to provide a novel arrangement of tubes capable of e'xpanding or contracting without danger 'of injury to any of the parts; said tubes being 4disposed in sucha manner 'as to present a'large heating surface to the hot products ofconibustion.

Another object-.is to providedeflecting means whereby/the products of combustion can be directed or spread laterally among the tubes prior to the escape o'f the hot products from the heater.

With these and other objects in view the invention consists of certain novel `features of construction and combinations of parts which Will be hereinafter more fully described and pointed out in the claims.

and a hot Water compartment 4i.

In the accompanying drawings is shown the preferred forni of the invention.

In said drawings.: Figure 1 is a detail view of the header and some of the pipes of the heater, the saine being removed from the jacket or casing; and Fig. 2 is a longitudinal Referring tothe figures i. by referring to Fig. 2 that said compartment Llapsthe upperiend of the cold Water compertinent soas to permit thevpipes 7 to extend upward from the top of the header 1.

are openings S disposed in staggered relation adjacent the sides and top'of the header.

Secured Within each of these openings is a return tube 9-having a cap 10 secured upon its free end for closing' the saine and each of these tubes opens into the hot Water compartment 4. All of the tubes are preferably parallel and form an archextending along the sides and over the tfop of the fire box 11 of the heater.

A series of openings 12 similar to the openings 8 are formed Within the inner face of the header 1 adjacent, and along a line parallel with, the bottom of said header, and secured Within each of these openings is a return tube 13 similar to the tubes 9 and having a cap 14 at its free end constituting a closure therefor. These tubes 13 form the grate of the heater and each tube opens into the hot Water comvpartinent 4. A faucet 15 is preferably connected to the free end of one of the tubes 13 and by means thereof hot Water may be drawn from the heater for domestic purposes.

The partition 2 is formed Witha plurality ofopenings 16 each of Which is dis osed in aliiement with the center ofv one of t e openings 8 and 12. Secured Within each opening 16 is one end of a pipe 17 which extends longitudinally Within the center of theadjoining tube 9 01x13 and terminates at a oint removed from the cap thereof. lt Wi thus be seen thatthe pipes 17 serve to convey cold Water from the compartment 3 tothe closed ends of the tubes 9 and 13 from which it returns through said tubes to the compartment 4. A deliecting plate 18 is preferably secured Within the casing 19 of the heater and between certainof the tubes 9 for the purpose of spreading the products of combustion prior to their escape through the outlet fiue 20.

It is of course obvious that when Water is admitted to the compartment 3 and the entire system filled the Water contained Within the various tubes and flues Will be quickly heated by the products of combustion With-. in the fire box 1 1. A Icirculation will thus be established and the cold Water Will be conveyed from compartment 3 to the closed ends of tubes 9 and 13 and will then return to compartment 4 through said tubes. During this return flow the water Will contact with surfaces which are directly lheated by the products of combustion and theWater While returning to the header Will heat the pipes 17 and raise the temperature of the cold Water therein before the same is discharged into 'the tubes. Owing to the elicient circulation pact and durable in construction andthe larts thereof can not readily get out of order. he arrangement or tubes disclosed presents -an extensive heating surface to the products 'of combustion and inasmuch. as these tubes extend entirely around the `re boX, and as the hot water compartment 4 is disposed di-l rectly at one end of said compartment the temperature of the water can be quickly raised and the amount of Juel necessary to obtain-efficient results is reduced to the minimum.V

lNhat is claimed is:

' In a heater the combination with a header comprising a hot water com artment and a cold water compartment; o't a plurality of return tubes communicating with and eX- tending from the hot water compartment, a closure upon the free end of each tube, a return pipe extending from the cold water compartment and into each tube, said pipes being disposed. to discharge water into the tubes adjacent their closures, certain of said tubes being disposed in a horizontal plane to constitute a grate and the remaining tubes being disposed along curved lines 4extending fromv the sides and over the grate, and a defleeting plate interposed between the grate tubes and the tubes thereabove for directing products of combustion laterally among the tubes-` ln testimony that I claim the Jforegoing as my own, I have hereto alixed my signature in the presence of two Witnesses.
